SPECIFICATION forming part of Letters Patent No, 384,310, dated .Tune12, 1888.

Application filed August 22, 184,7. Serial o. 2117,o6l. (No model.)

To all when?, it may concern.-

Be it known that I, SAMUEL DIsBRoW, a citizen of the United States,residing at Lewis, in the county of Cass and State of Iowa, haveinvented certain new and useful Improvements in Potato-Pleas; and I dodeclare the following to he a full, clear, and exact description of theinventiomsueh as will enable others skilled in the art to which itappertains to make'and use the same.

The object of this invention is to provide a plow which may be used fordigging potatoes, and one which will turn the potatoes out of the groundwithout injury and will not turn the earth upon them again, or, in otherwords, cover the potatoes by a furrow after they have been turned out ofthe earth.

The improvements will be fully understood from the following descriptionand claini,when taken in connection with the annexed drawings, in whichFigure l is a side elevation of a plow constructed according to myimprovements. Fig. 2 is a horizontal sectional view of the same, takenon the plane indicated by the dotted lines rv .c of Fig. l; and Fig. 3is an inverted plan View with the beam and handles removed.

Before describing the details ofconstruction- I desire to say that I amwell aware that various constructions of plows have been devised fordigging potatoes, in some cases the blades being arranged in a mannersimilar to mine and round straightbars or rods are used to form themold-board. This construction. is very objectionable in some sections ofthe country, and especially where stumps are numerous, as stumps andweeds are liable to injure the mold-boards or fenders thus formed; and,again, when some land becomes wet and sticky it will stick to the barsand ride over them and into the furrow.

Referring by letter to the said drawings, A B indicate the blades, whichare of a similar construction. These blades have a tapering forward endand their adjacent edges are cut away so as to meet each other acuteangular, as shown.

Each blade A B has secured to its point portion, on its under side andin a horizontal plane, a shoe, C,which extends rearwardly,and

serves the additional function of supporting the beam and also receivingthe inner ends of brace-arms, which brace the rear ends of the blades,as will be presently explained. It will be observed that the blades orshovels have a slight outward inclination, being held in this positionby means of arms l). These arms havethei r outer ends bolted to the rearunder sides of the blades, and after being carried in wardly in anelevated position are bent downwardly and secured on each side of theshoe or drag by the sanne bolts that secure the two sections ofthe saidshoe together.

E indicates the standard,whieh is secured to the said shoe or drag inadvance ofthe bracearms; and F indicates a vertical support for thebeam, which is also secured to the shoe in rear of the said arms. Infront of the standard I provide a guard, G, which hugs the saidstandard, as more fully shown in Figs. l and 2. Along the inner edge andsecured to the under side of each blade I secure gnardbars a, whichcomprise the fender or mold board. These bars are of flat contour anddiminish in height from front to rear of the plow. These bars areprovided at their lower ends with an eye for attachment by means of abolt to the inner under sides of the blades, and from this point theycurve inwardly and thence ontwardly, as shown, so that they will notallow earth to discharge into the furrow.

Having described this invention, what I claim is* The improvedpotato-plow herei n described, consisting of the inclined blades, theshoe or drag seen red thereto, as shown, the curved bracearms secured attheir outer ends to the under rear edges of the bladcs,and lheirinnerends secured to the said shoe bythe bolts which unite them, thestandard, and also the rear brace for the beam, supported by the saidshoe, the guard on the standard, and the flat curved bars secured attheir lower ends to the under inner elevated edges oi the blades,substantially as specified.

In testimony whereof I aliix mysignature in presence of two witnesses.

SAMUEL- DISBROW.
